INDIA-RUBBER SOLES FORBOOTS AND SHOES.

Specification of Letters Patent No. 10,008, dated September 13, 1853.

To alt whom t may concern Be it known that we, JOHN Or-IrLooT'r and ROBERT SNELL, of the city of Brooklyn, county of Kings, and State of New York, have invented a new and useful Improvement in India-Rubber Soles for Boots and Shoes; and we do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making part of this specication, in which- Figure l, is a side view of a ladys indiarubber sole boot, constructed according to our improvement. Fig. 2, is a longitudinal section of the same. Fig. 8, is a view of the under side of the sole; and Fig. 4, is a transverse section of the same.

Similar letters of reference indicate corresponding parts, in each of the several figures.

India-rubber is, in very many respects, better suited than any other material for the soles of boots and shoes, for winter wear; but owing to the difficulty of uniting soles of this material, with the uppers, when made of leather or of the usual materials, it has never been brought into this use, except for the soles of overshoes, whose upper parts also are of the same material. This improvement is intended to overcome these difficulties and make soles which are capable of being neatly and firmly united to the uppers.7

The nature of our invention consists in making the sole of three parts, viz., the india -rubber sole, a leather lining, and a leather border. The india-rubber sole is made smaller than the sole, or 4portion of the sole of the boot or shoe which it is intended to cover; and it has its edges beveled off thin all around. The leather lining is of the full size of the sole or piece required, and is united to the upper side of the indiarubber sole, all over, by waterproof adhesive material, leaving a margin extending all around beyond the edges of the india-rubber sole. The leather border consists of a strip of leather of about the same thickness as the india-rubber sole, and is of such width as to extend from the edges of the leather lining, and overlap the beveled part of the india-rubber; that part which overlaps the india-rubber, is beveled, so that its outer face will be level with the outer face of the india-rubber; this border extends all around the sole or piece, and is united, by the same 'material as the leather lining and indiarubber, with the margin of the leather lining and with the beveled part of the indiarubber. The three parts thus make a solid sole, of uniform thickness, with an indiarubber center, and leather edges, which may be secured to a boot or shoe, by sewing, cementing, or pegging, in the same way as a common leather sole; the edges being hard and stiff, protecting the india-rubber and presenting the same appearance as the edges of an ordinary sole.

A, in the accompanying drawing, represents the india-rubber sole, whose outline is indicated by the dotted lines in Fig. 3, and the bevel of its edges in Figs. 2, and 4.

B, (Figs. 2 and 4,) represents the piece of thin leather, applied to its upper side, leaving a margin, a, to the eXrtent shown outside the dotted 'line in Fig. 3.

C, is the leather border, which is applied to the under side; this is formed either of a strip of sole leather, bent into shape, and joined at its ends, or of a piece the same size as, B, with an opening cut in it, smaller than the india-rubber, so that it will cover the edges of the latter. The beveled parts of the india-rubber, A, and the border, C, are shown in Figs. 2, and 4. rlhe material we employ for uniting the india-rubber sole, lining, and,V border, is a solution of indiarubber; but any adhesive material which is suliciently tenacious and waterproof, will answer the purpose. The three parts, A, B, C, may be further secured to each other, by a row of stitching between the outer edge of A, and the inner edge of, C; this will not be necessary in all cases, but may be used as an additional means of security against separation. The sole in the state now described, is ready for use.

In order to make the bottom of the boot or shoe perfectly waterproof, it is preferable that the sole should be attached to the upper by waterproof cement; but it may be sewed or pegged, and when attached is trimmed oft' in the same way as a common leather sole.

A sole thus made combines all the advantages of an india-rubber, and leather sole, without the disadvantages of either. It is light, soft, and pleasant to wear, and perfeet-ly waterproof, and is not likely to lose its proper shape, or to separate at any point from the bootor shoe.

Any portion of the sole may be made in this Way; but the two pieces of leather, B, and, C, should always have their margins extending beyond, and united together, all around the outside edge of the india-rubber.

What We claim as ourl invention, and desire to secure by Letters-Patent, is,

Constructing the Whole or any portion of the sole of a boot or shoe, substantially as described, of india-rubber, With its inside and edges covered and protected by leather, 10 Which is united with it by any Waterprool cement, with or Without stitching, andforms a hard, firm, leather edge.
